A circuit where there is a break. Row 1, Col 1 What are protons? Have a positive charge. 1,2 What are the Poles? Ends of a magnet. 1,3 What is grounding? The transfer of electric charge to the ground. 1,4 What is a switch? A device that opens and closes circuits without unscrewing bulbs or disconnecting wires. 2,1 What are electrons? Tiny part of an atom that has a negative charge. 2,2 What is the magnetic force? The pushing and pulling behavior of a magnet. 2,3 What is an insulator? A material that doesn’t allow electricity to flow through it easily. 2,4 What is a cell? Another name for a battery. 3,1 What is a positive charge? Daly When an object loses some of its Double electrons it will have this charge. 3,2 What is a magnetic field? The invisible area that surrounds a magnet on all sides. 3,3 What is a resistor? A material that resists the flow of electricity. 3,4 What is a series circuit? A circuit where all bulbs will go out when one bulb is blown. 4,1 What is an atom? The smallest piece of an element that can still be identified as an element. 4,2 What is a loadstone? a “Leading Stone” or a natural, permanent magnet that contains magnetite. 4,3 What is a circuit breaker? Keeps excess charge from flowing through wires. 4,4 What is circuit? A path that electricity can move through. 5,1 What is the nucleus? The part of an element that contains the protons and the neutrons. 5,2 What are different charges? Two objects pull toward each other are said to have. 5,3 What is a conductor? A material that allows electricity to flow through it easily. FINAL JEOPARDY “Type of Magnets” How many points do you want to risk? Final Jeopardy Question This type of magnet that is produced by an electric current, usually a core of iron wrapped in a conductor. What is an Electromagnet?
